Encoding time computer specs

[rschildt]

I'm currently making a backup of Transformers 2 and re-encoding to fit the main movie onto a BD25 disk. Currently going okay, except it's been almost 23 hours! Is this typical? Granted, I don't have a speed demon for a PC. Still working with a P4 3GHz w/ 2.5GB memory and an ATI x1650 video card. Worked fine with standard DVD's, but BD taking 23+ hrs just won't cut it. I here most people are taking 4-5 hrs. What PC specs do they have?

Time for an upgrade?

Maybe? or just look @ the shear size of a BLU-RAY original movie @ "50GB". Do you realize SD DVD (A common store bought DVD) is a mere 8.5GB. BLU-RAY is "5" times this size. Then realize this, and I too did not think of this. We entertain compressing this 50GB disc to half this size and less 25GB, 8.5GB and even 4.7GB. All the while not factoring in the compressing and converting involved in this effort. After thoroughly educating myself through trial and error and determining that the average main movie portion of a BLU-RAY movie is usually more than 25GB (AND NOT BY ACCIDENT). I decided not to fool around. BLU-RAY is a major step up and to really enjoy backing up this HD media while saving time you need to invest in at least 1 50GB BD-RE DL rewritable BLU-RAY disc for your back ups. Next you will need a minimum 1tb hard drive external or internal. Next you will need to max out your PC's memory or ram capacity with at least 2GB ram. You will save a few hours by having these items. What you are omitting is compression and conversion time by using like media and having ample hard drive space and memory on your PC. Oh, my computer specs are:

SONY VAIO
O/S MICROSOFT WINDOWS XP
MEDIA CENTER EDITION
Running: SERVICE PACK 3
Intel PENTIUM 4 W/HT
CPU 3.20 GHz
2 GIGS OF DDR RAM
1TB of internal HD
1TB external HD
BUFFALO EXTERNAL
BLU-RAY MEDIA STATION
MODEL: BRHC-6316U2
BLU-RAY WRITER AND HD PLAYER
6X MAX BLU-RAY WRITE SPEED
BLU-RAY MEDIA:
SONY 2X 50GB BD-RE DL
SONY INKJET HUB PRINTABLE
2X 50GB BD-R DL

The key to the short times you see posted for some users is the video card and whether or not it supports CUDA/DXVA acceleration. If you plan on regularly compressing Blu-ray and want top performance, you need a PC with a fast FSB (1033MHz), lots (4-8 GB) of DDR3 RAM, a CUDA/DXVA- capable video card with a GB of dedicated DDR3 RAM and an i7 or quad core processor. 23 hours is still too long though, indicates something is wrong somewhere. My dual core laptop will compress the main movie of most Blu-rays in 5-6 hours.

Assuming you have an older PC, like mine the upgrades I mentioned may suffice. My approach saves me time as I don't really see the need to use the compression option as it takes way too much time on any PC (new or old). It takes me 30min on average to back up or rip BLU-RAY to file depending on the title and encryption and 3 to 4 hours to back up a movie only title to BLU-RAY 50GB DL disc media. You can find the BLU-RAY media type I mentioned here: http://nikonekoya.com at imported discounted prices.

Like Signals, my dual core 2.0 Ghz laptop with 4 Gigs of ram takes somewhere between 4 and 5 hours to compress a Blu-ray to a size suitable for a dual layer DVD. Granted I have a nVidia Geforce 9600M GT video card that makes use of the CUDA support offered by DVDFab, but 23 hours seems excessive. Even the free BD-Rebuilder offered on another site only takes my computer 12 hours (processes at 3 fps if you can believe it) for main movie and it doesn't support CUDA, but that's enough reason right there to use DVDFab.

24 hrs 7 min from beginning to end of burn. Looks and sounds good though. There's got to be improvements. Granted, BD's are quite a lot bigger, but DL DVD's to SL only took 20-30 minutes total.

How much ram do you have?...sounds like your memory is way low. What are you backing your title up to? What are your computer specs? Pardon the exclamation sign on the post above....I meant to select the light bulb.

You are downsizing to a BD25. I think what most people do here with a 4-5 hours effort is compressing down to a BD9. You're are processing approx 3 times the data to a BD25. That gives you something in the region of 12-15 h for a similar machine. But I'd also guess that most peolple having this figures (including myself) have dual core machines or better. Just for the sake of comparsion, assume that a modern dual core machine process twice the speed of the P4, and you end up with 25 to 30 h. So, I think doing a BD25 comression in 23 h, is probably more or less what you can expect with spec on your machine.

@ pes, I'd beg to differ (no flame) as my cpu specs are similar with the exception of memory (I suspect). There are many things to consider like what is the PC used for in general and is there any un-needed clutter hogging his PC's memory. What could also be an issue is his type of processor. My pentium 4 has HT (Hyper Threading) which was one of the last single core intel processors made before they went pentium -D duo-core. My computer has some of the multi-tasking characteristics of the duo-core processor and is ultimately a fast processor. I'd say get 50GB DL BD-RE rewritable BD media and you can't go wrong.

This is not unusual. RAM is not an issue, DVDfab doesn't need that much. Everything depends on CPU power.
I have a single core 2 GHz Pentium M.
Reducing "Watchmen" from 34 GB to 23 GB took about 26 hours. My Ati HD4650 (dvxa support) didn't help much.

The irony here is that you would think that compressing from 50GB down to 25GB would be faster than compressing from 50GB down to 8GB, since you're asking it to compress "less", but based on pes's comments, perhaps the opposite is true?

[LEGIN27]

@Scott. If it's taking that much time, quit. 23hrs is more than half of my work week (employed). Just go buy it. But serious, why all the compressing when you can use BD-RE 50GB DL BD rewritable media?

Well, LEGIN27, I think the whole purpose of the compression is to fit it on a 25gb disc, which is considerably more affordable than 50 gig.

and scott 23hrs. is WAY to long for a rip, ether consider upgrading your PC, or as an alternative use Tsmuxer.

[Reinhard62]

As I said, more than 20 hours is completely normal for compressing BD 50 to BD 25 if you have a single core CPU. Using another software (TsMuxer) won't make it faster.

And not everbody has the extra money to upgrade his/her computer.

Using BD 50 GB is certainly NO alternative. The cheapest ones I've seen cost 11 Euros - whereas you get almost all BD movies for about 12 - 13 Euros.

To be quite honest, I cannot see much future in "BURNING" to removable media anyhow.

With the advent of hard disk and network Media Players that will play most formats, 1Tb of storage at less than $100, why would you even bother?

Get a life !!!
